Unburnt hydrocarbons from worn spider fuel injectors often cause internal ceramic sintering, leading to partial substrate meltdown, elevated exhaust backpressure, and downstream catalyst efficiency trouble codes (P0420\/P0430). Additionally, the original aluminized casings corrode around the secondary welds, allowing pre-sensor ambient air leaks that skew closed-loop fuel trim calculations and degrade fuel economy under load.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis center-position converter is engineered with a high-efficiency washcoat applied to a robust ceramic honeycomb substrate, maximizing precious metal surface exposure to effectively reduce CO, NOx, and HC emissions without bottlenecking exhaust gas velocity. The assembly features a heavy-gauge \u003cstrong\u003ealuminized steel\u003c\/strong\u003e body with seam-welded joints to resist road salt brine and thermal fracture. Designed as a direct drop-in assembly, it retains OEM-spec slip-fit and flanged mating surfaces to bolt straight to factory downpipes and intermediate exhaust pipes without torching or custom fabrication.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cdiv style=\"overflow-x: auto; margin-bottom: 20px;\"\u003e\n  \u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px; min-width: 300px;\"\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e1996-1998 GMC C\/K Trucks\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003eVortec 4300 (L35) \/ Vortec 5000 (L30) \/ GMT400\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e200-230 hp \/ 250-285 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e50275, 795110, 9720\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n\u003c\/div\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1996-1998 GMC C1500 Pickup 4.3L V6 (Vortec 4300 L35)\u003c\/li\u003e\n  \u003cli\u003e1996-1998 GMC C1500 Pickup 5.0L V8 (Vortec 5000 L30)\u003c\/li\u003e\n  \u003cli\u003e1996-1998 GMC K1500 Pickup 4.3L V6 (Vortec 4300 L35)\u003c\/li\u003e\n  \u003cli\u003e1996-1998 GMC K1500 Pickup 5.0L V8 (Vortec 5000 L30)\u003c\/li\u003e\n  \u003cli\u003e1996-1998 GMC C2500 \/ K2500 Pickup 5.0L V8 (Vortec 5000 L30)\u003c\/li\u003e\n  \u003cli\u003eNote: Fits Center position only; not compatible with 5.7L V8 or CARB emissions states (CA, NY, CO, ME).\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003ch4\u003eDoes this fit the GMT400 C\/K Trucks?\u003c\/h4\u003e\n\u003cp\u003eYes, this is a direct fit for the 1996-1998 GMC C\/K Trucks equipped with the \u003cstrong\u003eVortec 4300 (L35)\u003c\/strong\u003e or \u003cstrong\u003eVortec 5000 (L30)\u003c\/strong\u003e engine.\u003c\/p\u003e\n\n\u003ch4\u003eWill this unit clear OBD-II catalyst efficiency trouble codes?\u003c\/h4\u003e\n\u003cp\u003eYes, its high-load ceramic substrate restores exhaust gas conversion efficiency to clear P0420 and P0430 diagnostic codes when paired with operational downstream oxygen sensors.\u003c\/p\u003e\n\n\u003ch3\u003eThe GMC Heavy-Duty Standard\u003c\/h3\u003e\n\u003cp\u003eConstructed to handle continuous high-exhaust-temperature towing demands, this converter delivers the thermal resilience, backpressure reduction, and durable casing integrity needed to keep your working truck pulling reliably on the job site.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":67538078466296,"sku":"DS-EU7G1C1QI","price":179.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/catalytic-converter-for-gmc-c-k-trucks-1996-1998-4-3l-5-0l-center-1.jpg?v=1790622327","url":"https:\/\/performancechiptuning.com\/fr\/products\/catalytic-converter-for-gmc-c-k-trucks-1996-1998-4-3l-5-0l-center","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
